UNITED sr frEsrnrnnrorrion f H JAMES F. LYONS, or soivrnnvinnn; MAS A fi I To all whom it may concern:

Be it knowntha t I, JAMu's F. LYoNs, a

citizen of the United States residing at .Line street, Somerville, in the county of; Middlesex and State- 0f Massaehusetts,have

invented a new Spirit-Leveljof; which the following is a specification.

This: invention relates to improvements; in spirit-levels andhas for its object to provide a level in which the angle of the spirit glass may be varied relatively to the stock of said level and secured in the posi;

tion desired.

;The invention consists inthei combination and arrangement of {parts whereby the above obgect and cert-am otherob ectshereinaft-er appearing may be'attained, as set forth in the following specification and particularly pointed out in the claims.

' Referring to the drawings: Figure 1 is a side elevation of a level with two devices embodying my invention show-n in connection therewith, portions of the stockof said level beingbroken away to save space in; the drawings. -"Fig. 2 is an enlarged sectional elevation taken on line 22 of Fig. 1 and viewed in the direction of the arrows on said line. Fig. 3Mis a section taken on line 33 of Fig: 2 as viewed in the; direc tion of the arrows on said line. Fig. 4 illustrates in detail. the semicircular members constituting the ring upon which the spirit glass casing is arranged to revolve. Fig. 5 r is a detail vlew of one section of the cylini drical bushing.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 6 is the stock which may be of any suitable material, such as mahogany or the like and provided with av plurality of holes 7 extending laterally therethrough. In each of said holes 7 is arranged a bushing 8 formed in two cylindrical sections 9 and 10, the outer ends 11 the respective faces of said stock 6.

A ring 12 consisting of two semicircular members 13 and 14 is arranged within the I hole? intermediate the adjacent ends 15 of said bushing sections, each of said sections contacting with said ring. The diameter of the hole through said ring is substantially smaller than the internal diameter of said bushings, while the outside diameter of said ring is substantially equal to the outside diameter of said bushings, or in other words,

ing within the bushing 8 and permitting said casingto be angularly adgusted therein, said casing being "slightly shorter than the in- H ternal diameter offsaid bushing and the distance between the inner ends of said .slots eter of the ring 12, thereby permitting said arranged in said bushing within a metal.

which is of the usual constructionvsubstantially filled with spiritswith theexception of 18 to expose thejcentralportion of said I thereof adapted to receive opposite portions being slightly less than the internaldiamcasing to be freely adjusted an 'ularly within said ring or at leastsothat there will be, I no binding between sald cas ng and said" bushing and; the inner periphery of said ring. Means are provided "for securing said erally thereof iniholes 21 in saidcasing and the ends of said casing betweenthe face 24 face, of said casing. The inner ends of said of said casing and the ends 23 of said screws bytongues 26 formed upon one of'th'e sections of the bushing 8, preferably the section 9 and projecting laterally from the secured to the stock 6 byscrews 27. The

by screws 27 to the stock 6 thus firmly'binding and securing saidring inits position within the hole 7 casing to the ring 12 at a; predetermined angle relatively to the stock 6, said means,,

consisting preferably of;screws '20 arranged adjacentihe. ends of said casing and latl having screw-threaded engagement with nuts 22, which substantially, fit the portions of of'the' ring 12 and theadjacent inner sura I 'screwsengage the face of the ring adj acentf said nut and as said screws are'rotated said; i nuts will be forced against the inner walls more firmly engage said face 24: of said ring-.

, As the casing 17 is secured to the ring to 1' edge 15.thereof,:While said bushing is in turn notches25 which are adapted to be engaged section 10 of said bushing is likewise secured 1 In assembling the device one of the sec-j tions of the bushing 8,' preferably 10, is

placed within the hole 7 and secured therein by screws 27. The two sections of the ring 12 are then assembled, one in each of the grooves 19 inthe ends of the casing 17 after which said casing and said ring is placed in the hole 7 against the end 15 of the sections 10 of said bushing. The other section 9 is then inserted in the hole '7 from the opposite end with tongues 26 engaging the notches 25 and secured in such a position by the screws 27 I With a plurality of devices hereinbefore described shown attached to a single stock it will be readily seen that the spirit glass casings may be adjusted at v'arious angles relatively to said stock to permit said stock to be used to plumb or level certain surfaces or I to set surfaces at any predetermined angle relatively to a horizontal or vertical plane.

Having thus described my invention what I claim and desire by Letters Patent to secure is:

1. In a device of the class described the combination of a stock provided with a hole extending laterally therethrough, a bushing formed intwo cylindrical sections arranged in said hole, and a ring consisting of a pair of semicircular members arranged in said hole intermediate the adjacent ends of said bushing sections, a spirit glass, a casing for said spirit glass adapted to engage and to be angularly adjusted in said ring, and means adapted to secure said casing at a predetermined angle relatively to said stock.

2. In a device of the class described the combination of a stock provided with a hole extending laterally therethrough, a bushing arranged in said hole and formed in two consisting of a pair of semicircular members interposed between the adjacent ends of said sections means on sald bushing adapted to engage said ring and lock the same against displacement, a spirit glass, a casing adapted to contain said glass, said casing having longitudinally arranged slots at opposite ends thereof adapted to receive opposite portions of said ring and permit said casing to be angularly adjusted therein, and means contained in said casing adapted to engage'saidring and lock the same at a predetermined angle relatively to said stock.

3. In a device of the class described the combination of a stock provided with a hole extending laterally therethrough, a ring arranged in said hole and secured to said stock, a spirit glass, a tube arran ed to be angularly adjusted within'said stock and adapted to contain said spirit glass, said sections each secured to said stock, a ring 40 tube having longitudinally arranged slots at' opposite ends thereof, adapted to receive said rmg, and guide said tube during the angular ad ustments thereof, nuts arranged in the ends of said tube adjacent said slots respectively adaptedto substantially fit that portion of said tube, and screws having screw-threaded engagement with said nuts and adapted to engage said ring and lock said casing at a predetermined angle relatively to said stock.
